BYRON O. BRADLEY, OF CHICAGO, ILLINOIS.

TONGUELESS CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 334,688, dated January 19, 1886.

Application filed November 27, 1883. Serial No. 112,986. (No model.)

To all whom it may concern.-

Be it known that I, BYRON C. BRADLEY, residing at Chicago, in the county of Cook and State of Illinois, and acitizen of the United States, have invented new and usefuLIm provements inTongueless Cultivators, of which the following is a full description, reference being had to the accompanying drawings, in which-.

Figure 1 is a side elevation with one of the wheels removed and the ends of the handles broken off; Figs. 2 and 3, side elevations of the wheel-spindle and draw-bar bracket, showing,respectively,the runner or drag-bar in its elevated and depressed positions; Fig. 4, a rear elevation of the machine with the beams removed; Figs. 5 and 6 details of the stop for holding up the arch; Fig. 7, a detail showing the construction of the pipe-box and the beam stirrup or bracket.

This invention relates, principally, to the construction and operation of the runners or drag-bars by which the plow-beams are'held elevated, and to means for retaining the arch of a tongueless cultivator in its vertical position, and has for its objects to improve the construction of the arch or frame, to insure a positive retention of the runners or drag-bars, either when elevated or depressed, and to maintain the arch in its vertical position whether the beams are raised or lowered, by the simple act of raising and lowering the beams; and its nature consists in the several devices and combinations of devices hereinafter described, and specifically pointed out in the claims as new for attaining the objects named.

In the drawings, A B represent the arch formed of two fiat metalbars, each having a curved or elevated central portion and ahorizontal portion, A B, on each side with a space between them for the location of the beamcoupling and form a support for the bracket of the wheel-spindle and draw-bar, and,as shown, these parts are held apart at the center of the arch by a piece, a, riveted or otherwise secured between the bars.

0 represents standards or posts, one on each side of the arch, located between the horizontal portions .A Bi at the outer end, and secured in place in any suitable manner, and, as

rying the wheel-spindle, having on its exterior face a rib, c, for strengthening purposes, with an enlarged portion, a, to form a bearing for the pivot of the runner, and, as shown, the lower end of the flange c is expanded to form a half-box, d, and furnish a sand-box for the inner end of the wheel-hub.

E is a pin or rod by which the bracket D is pivotally attached to the ends of the horizontal portions A B of the arch. As shown, the bracket D has inwardly-projecting ears b at the top and bottom, between which the ends of A B are passed, and through which ears and the ends the pin or rod E passes, forming a pivotal connection by which the bracket is free to swing forward and back.

F G represent arms cast or formed with the bracket D, and extending out therefrom and joined at their outer ends and forming the draw-bar, having at its outer end, as shown, a hook, e, for the attachment of the draft.

H is the wheel-spindle, located at the lower end of the bracket D.

I represents wheels, one for each side of the machine, having a huh, I, which receives the spindle H, so that the wheel is controlled by the draft.

J represents the runners or drag-bars, one for each side of the machine, and pivotally attached to the inner face of the bracket D by a suitable pin' or pivot, g, and the end of the runner or drag-bar which projects beyond the pivot is provided with a notch, f, as shown in Figs. '2 and 3, and the ground end J of each runner is widened to present a greater bearing-surface.

K is a latch, one pivoted to each of the brackets D on the innerface by a suitable pin or pivot, h, and in such manner as to have its free end engage and lock the runner in its elevated position, as shown in Fig. 2, and to engage with the notch f and lock and hold the runner in its depressed position, as shown in Fig. 3. As shown, the latch, when down. and

holding the runner elevated, rests on a flange formed on the lower edge of the bar G of the draw-bar, but it might be held by a pin or stud properly located for that purpose.

L is a pipe-box mounted on a rod, one on each side of the machine, and to which the coupling for the plow-beam is secured.

M is a flange 011 the inner end of each pipebox, cast or formed with the box,and having in the form of construction shown a cut-away portion adjacent to the periphery of the box, so as to leave a ledge, i,with terminal ends 2', which ends, when the parts are together, come in line with the vertical portion of the bar B, so as to strike against the edge of such bar as the pipe-box is rotated in raising and lowering the beam. This flange M forms a stop for the arch, and prevents it from falling over as the beams are raised or lowered by reason of the edge of B engaging either one or the other of the terminal ends i, thus holding the arch in a vertical position. As shown, the stop M is made of a single piece, but it is evident that the flange portion might be a separate piece screwed or otherwise secured in place.

N is a stirrup portion of the beam-coupling, having a central socket,j, to fit over the pipebox L, which socket is open on one side and has projecting cars j, by means of which and a clamping-bolt the stirrup can be secured firmly in position, and, as shown, in order to secure a firm connection between the stirrup and the pipe-box and prevent slipping the pipe-box is provided with a tongue or feather,

j, which, when the parts are together, fits between the open ends of the socketj, as shown in Fig. 7. The stirrup has rear projecting arms, is, between which is pivoted the forward end of the plow-beam.

0 represents the beam plate or plates on the foward end of the plow-beam, and having a socket, a, which clasps the box 1 between the arms 7., which box is held in position by abalt, in, so as to allow lateral swing ofthe beam.

1? represents the plow-beams, each having a handle, Q, andstandards Q, carrying shovels Q, as usual.

R represents hang-up arms, one on each side of the arch, and extending out rearwardly therefrom, and having in their outer end a notch, 12, to receive a ring, 0, attached to the plow'beam, by means of which the beam is held suspended. The forward end of each arm R is secured between the bars A B of the arch, as shown in Figs. 1 and 4.

The features belonging to this invention pertain to the runners or drag-bars and the stops for holding the arch in position, and the operation of these parts, therefore, is all that is necessary to describe, as the other parts operate in the usual manner of corresponding parts of cultivators of this variety.

When the machine is moving from place to place or is not in use, the beams are hung up by slipping the ring 0 onto the arm R in the notch 12, and this elevating of the beams turns the pipe-box L and brings the upper terminal end, 5, of the stop M in contact with the edge of B, forming a support against the backward falling of the arch and maintaining it in a vertical or nearly vertical position, and when the beams are thus elevated the drag-bar travels on the ground, and is in the position shown in Fig. 3, with the latch K engaged with the notchf, holding the runner or drag-bar firmly against the travel of the machine. \Vhen in use, the beams are lowered as required, turning the pipe-box L and bringing the lower terminal end, i, of the stop M into engagement with the edge of B and holding the arch in its vertical or nearly vertical position with the plows at work, and when the plows are at work the runners or drag-bars are elevated, as shown in Fig. 2, in which position the latch K engages the edge of the runner or drag-bar and holds it firmly in its elevated position. The dragbar is lowered, when elevated, by throwing the latch up and leaving the drag-bar free to be turned down at its ground end, and when down the latch is thrown over to engage with the notch f, and when the runner or drag-bar is raised the latch is again thrown back, releasing the runner and allowing its ground end to be turned up, and when up the latch is dropped down to engage its edge.

By projecting the end of the drag-bar beyond the pivotal point and providing the latch K to eoact therewith it will be seen that the drag-bar is maintained in its elevated or depressed position by the same locking device, and by providing the stop M on the end of the pipe-box which carries the beam it will be seen that the movement of the beam operates the stop to bring it in proper posi* tion to support the arch with the beams elevated or at work.

A stop or pin, 7', is provided for each runner or drag-bar to limit the downward movement of the ground end. This pin is located to allow the upward withdrawal of the latch from the notch to be had, but prevents the end of the drag-bar from dying out far enough to let the latch drop down out of the notch; and this pin or some other form of stop is required for this purpose, as otherwise the drag-bar might drop into a depression at the ground end and disengage the latch, allowing the drag bar to be unsupported and be non-acting.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination of the wheel-spindle bracket, the drag-bar J, having a projecting end provided with a notch, and a latch, K, for locking the drag-bar in both its elevated and depressed positions, thesaid drag-bar and latch being pivoted to the wheel-spindle bracket, substantially as described.

2. In a cultivator, the combination of an arch, a pipe-box provided with a slot to engage said arch, a drag-bar or runner, and a locking pawl or device for the drag-bar or form vertical portions between the parts A runner for holding the arch in avertieal posi- B, the posts 0, and the pi pe-box L, substan- 10 tion and supporting the plowbeams whe tially as described. elevated, substantially-as described.
